Table 1

List of proteins that were present in at least 4 volunteers and which expression has been changed in statistically significant manner (<0.05) as determined by the variance analysis and the Wilcoxon test. Ratio = exposed sample expression/sham sample expression.

* prevalence shows in how many volunteers, out of 10, was detected given protein spot;

+ variance analysis might be unreliable because of small numbers of cases and potential violations of model assumptions;
